TanDEM-X Science Service System

The TanDEM-X Science Service System is a web interface for the submission and evaluation of scientific proposals.
The portal is the main interface for Principal Investigators to define their acquisition requests.
It is further used to monitor and track the status of submitted proposals and is a tool
for the science coordination team to help organize the science user community of TanDEM-X.

(since 2016/12/13): TanDEM-X Digital Elevation Models Global DEM Proposal submission available under 'General Proposal Submission'
This proposal call under 'General Proposal submission' rules aims for the first scientific exploitation of the final & global DEM product of the TanDEM-X mission.
The TanDEM-X DEM is the main DEM product of the TanDEM-X mission and is available for all land masses, including Antarctica, and all latitudes above 60° North.
The call is dedicated to the data of the two highest posting classes (12m & 30m). The 90m product variant is not available by this call, and will be offered later with simplified procedures.

Please check the following documents:

Announcement of Opportunity: TanDEM-X DEM:
This documents gives a quick introduction on how to submit a DEM proposal, and explains all the constraints and peculiarities (e.g. quota limits, security regulations given by German law) of the call.

TanDEM-X DEM status interface:
An interactive online map interface, which in addition delivers quicklooks of the DEM tiles. Tiles in the inner part of Antarctica (below -85°) are due to the Mercator projection not displayed; please check the KMZ file instead for those tiles.

License Agreement:
The license agreement defines the terms of use for TanDEM-X data. It has to be accepted and signed by the user, when the proposal is approved.

COFUR service fee price list:
The COFUR price list shows the service fee, which will be charged for all TanDEM-X products (e.g. DEM, IDEM, CoSSC), if the science proposal is submitted after the due date or under 'General Proposal Submisson' rules.

Browser compatibility and other constraints:
This page is tested with Firefox, and the Microsoft Internet Explorer. Google Chrome might work. The Apple Safari browser is not supported in the moment.
Some interfaces of the proposal web form require the support of the Google Maps API. If your local network or your national security regulations do not support the usage of Google services, try to make use of a proxy page.

Important documents can be accessed from the left side menu.
The TanDEM-X Science Plan gives an
overview about the scientific objectives of the TanDEM-X mission.
The document TanDEM-X Science Service System Manual
provides both a summary and a detailed description of the procedure for submitting a scientific CoSSC proposal.
In addition it guides users through the acquistion request for TanDEM-X image products

(2012/02/01): TanDEM-X Experimental Product Description
This document gives an overview of the variety of experimental products generated from TanDEM-X
acquisitions, and contains a description of the Co-registered Single Look Slant Range Complex (CoSSC) product structure and format.

(2012/07/05): CoSSC Generation and Interferometric Considerations
This document is intended to clarify how the Coregistered Single look Slant range Complex (CoSSC) are generated and what are
the particularities of the monostatic active and bistatic passive coregistered images.

New science users need to register first to get an account
(see also the side menu link 'Investigators Registration'). After submission of the registration form an automated email is
created, providing a link to a verification page.
With the successful submission of the verification form the user account will be created, and the user is registered.

Registered science users may login using the form fields within the left side menu.
The proposal interface can be accessed after login by selecting the link 'Investigator' on the left side menu.

GENERAL Proposal Submission

This permanent proposal submission interface is open during the life time of the TanDEM-X mission. You can apply via science proposal for all main products of the TanDEM-X mission,
which have been released so far, also outside of a dedicated proposal call. But please note that
a service fee might be charged for the delivery of the data, please check the COFUR service fee price list.
The following products are available under General proposal submission rules:

Global DEM (DEM) Products: This AO aims for the first scientific exploitation of the final & global DEM product of the TanDEM-X mission. The TanDEM-X DEM
is the main DEM product of the TanDEM-X mission and is available for all land masses, including Antarctica, and all latitudes above 60° North.
The AO is dedicated to the data of the two highest posting classes (12m & 30m). The 90m product variant is not available
by this AO, and will be offered later with simplified procedures. For the delivery of the DEM data, which are assigned to positively evaluated proposal, a service fee according to the COFUR price list will be charged.
Please check the DEM-AO document for important information including a how-to manual: Document: Announcement of Opportunity: TanDEM-X DEM

CoSSC Products: This type of proposal gives access to interferometric products of the TanDEM-X mission, which have been acquired for the global DEM, as well as for scientific proposals.
An approved proposal includes both the (quoted) access to archived products, as well as the request for new interferometric data takes over specific test sites.

Intermediate DEM (IDEM) Products:
The Intermediate DEM datas sets are based on the first mission year coverage, and are available for some selected regions only.
You might still submit a proposal for this DEM product, if you are interested in this kind of data. The Intermediate DEM products might have gaps, especially for high mountain areas.
The deliverable Intermediate DEM tiles can be inspected by a Google Earth kompatible KML layer here.

Global TanDEM-X DEM-AO

This AO and proposal call aims for the first scientific exploitation of the final & global TanDEM-X DEM product of the TanDEM-X mission.
The call is dedicated to the data of the two highest posting classes (12m & 30m). Please note that the 90m posting class product will be made available
at a later date and with simplified procedures. The data provision is free of charge for all approved proposals submitted before due date. For proposals arriving after
due date a service fee, according to the
COFUR price list will be applied. The status overview of the deliverable tiles is offered by an online map interface or a Google Earth compatible KML layer.
Please check in addition the following documents:

This AO aims for the first scientific exploitation
of DEM products (Intermediate DEM) of the TanDEM-X mission. Please note that the Intermediate DEM is not the final DEM product.
The deliverable DEM tiles for this proposal call, produced for selected regions of the globe and solely based on the first global coverage of the mission,
are giving a first impression and a preview for the DEM products to come. There is a quoted access for the data
in the two highest posting classes (12m & 30m ),
while for the 90m posting class there is no quota limit at all. The data provison is free of charge for all approved
proposals submitted before due date. For proposals arriving after due date the
COFUR price list will be applied.
The deliverable tiles can be easily inspected by the KML layer here

SCIENCE PHASE AO

The TanDEM-X Science Phase is dedicated to the demonstration of innovative techniques and experiments
that have special orbital and imaging requirements in order to foster the development of new methods and applications.
The proposed projects are foreseen for a special mission phase, which will take place from October 2014 to December 2015.
A bundle of new interferometric operations modes for science user is available for this period.
The data provison is free of charge for all approved proposals submitted before due date. For proposals arriving after the official due date the
COFUR price list will be applied. Please also note that you cannot apply for all periods of
the Science Phase, due to data take planning procedures. For further information please contact us via email (tandemx-science@dlr.de).
